Goals of Treating Asthma Although canine allergic bronchitis (also called asthma) is uncommon in dogs, when it does happen it can be quite distressing to owners and to the affected animal.

Fortunately, a number of treatment options are available to help manage and minimize the consequences of this disorder. The goals of treating asthma are to identify and remove the inciting allergens from the dog’s environment if at all possible; they are usually something that the dog has inhaled. If that cannot be accomplished, a number of different medications are available to treat the condition symptomatically. Once the disorder becomes chronic, complete resolution of the cough is almost never possible. Treatment Options Once allergic bronchitis is suspected, the treating veterinarian will try to identify the underlying cause of the allergy attack so that it can be removed from the dog’s environment.

But beware -- and aware -- for clues that may indicate asthma, a potentially life-threatening condition in pets. As with humans, asthma in dogs is essentially an allergic reaction to something in the environment. Exposure to the allergen triggers inflammation and uncontrolled mucus or fluid production that may block or narrow airways to make breathing difficult. Cats are much more susceptible to asthma than dogs, but small canines are more vulnerable than larger breeds. Risk Factors. Dog Asthma (Allergic Bronchitis)
How Asthma in Dogs is Diagnosed The signs of allergic bronchitis, which typically include a dry, hacking cough, wheezing and shortness of breath, can be very frightening for dog owners and for their dogs.

Fortunately, veterinarians have a number of tools to help diagnose this condition so that effective treatment can begin. There is no single test that will conclusively confirm whether a dog has allergic bronchitis or some other type of respiratory disorder. A diagnosis of canine “asthma” is made based upon a number of things, including the dog’s presenting clinical signs, a thorough physical examination and history and ruling out other conditions that could cause or contribute to the symptoms. It can greatly help your veterinarian if you write down all the signs you notice in your dog and bring that list with you to your dog’s appointment.

When a dog has an asthma attack, he normally has trouble breathing. During asthma, the air passages of the lungs (the bronchi) fill up with heavy mucus.
